HEATING ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 349,534, dated September 21, 1886. Y

Applica-tion filed March 9, 1856. Serial No. 194,548. (No model.)

To @ZZ whom t may concern:

Be it known that I, SAMUEL SMITH, a citizen of the United States, and a resident of Silver Lake, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Heating Attachments for Stoves; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of a portion of a stove-pipe provided with my improved heating attachmentyand Fig. 2 is a vertical sectional view of the same,taken through two of the-pipes.

Similar letters of reference indicate corresponding parts in both the figures.

My invention has relation to that class of heating attachments for stove-pipes in which two conical chambers fit upon sections of the stove-pipe, and are connected by means of a number of pipes opening in the bases of the conical chambers, the stove-pipe sections entering the apices of the conical chambers; and

-it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letters A A indicate the two portions of stove-pipe,

upon which fit portions B and O of pipe, which respectively' enter the apices of the upper and lower conical chambers, D and E, which have their bases facing each other. The upper section, B, of pipe is provided with a damper, F, of the usual construction, by means of which the draft in the pipe and entire heating apparatus may be regulated,as in stove-pipes of the usual construction without `heating attachment. I The edges G of the bases of the conical chambers are bent over the langed edges ofthe tapering sides of the same, the said edges and flanges, which latter are lettered H, forming tight and simple joints between the sides and bases ofthe chambers. The bases of the chambers are formed with perforations I, arranged so that the perforations in both bases register with each oth- 5o er, and the tubes J, or flues which connect the bases and chambers, fit with their ends in these apertures. The upper and lower ends of these fines, where they t into the apertures, are formed tapering 'or conical, soas to 55 it snugly in the apertures, and the bases of the two chambers are connected by means of a rod, K, which'serves to draw the bases of the chambers toward each other, and to draw the apertures firmly upon the conical ends L 6c of the fines. This rod is preferably composed of two parts, which are formed with right and left hand threaded ends, upon which a correspondingly-threaded nut, M, fits, so that by turning the nut the chambers may be 65 drawn toward each other, the rods being secured in the centers of the bases of the chambers'.

It will be seen that as the smoke and heat, and other products of combustion pass up' 7o through the stove-pipe they will be retained and spread over acomparatively larger space in the chambers and dues, and come in contact with a larger surface than in the pipe, allowing the said products of the combustion to 7 5 give off their heat to the walls ofthe chambers and to the tubes, which will again radiate the heat into the room through which the pipe passes, and give off the heat to the air circulating vbetween the fines and around the cham- 8o bers, thus utilizing the heat, which otherwise would be wasted by passing up through the chimney into the air.

By tightening the nut upon the ends of the rods the joints between the flues and apertures 8g l in the chambers may be tightened, as the conical ends of the ilues will be forced more firmly into the apertures.

Having thus described my invention, I claim v and desire to secureby Letters Patent of the 9o In a heating attachment for Astove-pipes, the combination of two conical chambers having pipe-sections at the apices of the chambers, and having a number of registering 'aper- 95 tures in their bases, a number of dues having their ends tapering or conical and fitting in In testimonythat I claim the foregoing as my the apertures, and rods having rightand left own I have hereunto afiixed my signature in '4 hand screw-threaded ends and secured at the presence of two Witnesses.
